Answer:

?= 63.15789474%

Step-by-step explanation:

Use cross multiply

Set ?=x

$57 \times x = 100 \times 36 \\ 57x = 3600 \\ \frac{57x}{57} = \frac{3600}{57} \\ x = \frac{3600}{57} \\ x = 63.15789474$

Express the radical using the imaginary unit, i

Kipish [7]

Answer:

7i.

Step-by-step explanation:

Note : The given expression must be $\sqrt{-49}$ .

We have to write this radical value in the imaginary value.

The given value can be rewritten as

$\sqrt{-49}=\sqrt{49\times (-1)}$

$\sqrt{-49}=\sqrt{49}\times \sqrt{-1}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]$

$\sqrt{-49}=7\times i$ $[\because \sqrt{-1}=i]$

$\sqrt{-49}=7i$

Therefore, the required expression is 7i.
